Yeah, we aren't even calling ranlib directly, it goes through 'ar'
which doesn't expose any such option.  In any case that'd necessarily
be an OS-specific option.

I previously suggested that we should teach the build systems not
to build the foo_x86 and foo_aarch64 modules when not on those
architectures.  That was shot down for reasons that made no great
amount of sense to me, but I think it'd be fairly easy and clean.
